Democratic Rep. Ilhan Omar congresswoman from Minnesota clashed with Elliott Abrams, President Donald Trump’s new special envoy to Venezuela, at a heated House Foreign Affairs subcommittee hearing about the crisis in the South American country.

“In 1991, you pleaded guilty to two counts of withholding information from Congress regarding your involvement in the Iran-Contra affair, for which you were later pardoned by President George H.W. Bush,” Omar began during a House Foreign Affairs Committee hearing on U.S. policy towards Venezuela.

“I fail to understand why members of this committee, or the American people should find any testimony that you give today to be truthful.”

“If I could respond to that,” Abrams said, quickly leaning into the microphone.

“That wasn’t a question,” Omar shot back.

“It was an attack,” Abrams said his voice rising as Omar repeated that her statement was not a question. “I reserve the right to my time,” the congresswoman continued.
